Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# condition_filtering
> **Note**: This sub-skill covers one step of the Excel analysis workflow. For the full pipeline (file reading, row counting, large-file optimization, export), see the parent workflow SKILL.md.
Step1 执行多维度数据清洗与条件筛选，包含列名自动识别、RGB 颜色过滤、前缀匹配及正则提取。
```python
# 1. 自动识别同义列名并筛选非空值
target_cols = ['域名', '缩写', 'code', 'domain']
for col in target_cols:
if col in df.columns:
df = df[df[col].notna()]
break
# 2. 基于数值通道的精确筛选（如 RGB 颜色过滤）
# 技巧：多条件组合筛选时使用 & 符号
if all(c in df.columns for c in ['Red', 'Green', 'Blue']):
df = df[(df['Red'] == 0) & (df['Green'] == 0) & (df['Blue'] == 0)]
# 3. 基于字符串前缀筛选并进行数值转换计算
if '编号' in df.columns:
# 筛选特定前缀的项目
df = df[df['编号'].astype(str).str.startswith('TXL3')]
# 技巧：使用 errors='coerce' 处理无法转换的脏数据
df['val_a'] = pd.to_numeric(df['技工'], errors='coerce')
df['val_b'] = pd.to_numeric(df['普工'], errors='coerce')
df['total_val'] = df['val_a'] + df['val_b']
avg_val = df['total_val'].mean()
# 4. 基于特定分类值的筛选与统计
if '钢筋级别' in df.columns:
sub_df = df[df['钢筋级别'] == 'Ⅱ'].copy()
sub_df['target_val'] = pd.to_numeric(sub_df['屈服荷载'], errors='coerce')
avg_target = sub_df['target_val'].mean()

How to install
mdr add opensensenova/sensenova-skills/condition-filtering-and-large-file-optimization@sha256:cf8c6d664e0245baThe line at the top of this page pins the label git:20260426.f0ab496, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
